CROSS REFERENCE TO RELATED APPLICATIONS

This application is a continuation of U.S. application Ser. No.15/434,804, filed on Feb. 1, 2017, which claimed priority from U.S.Provisional Application No. 62/438,532, filed on Dec. 23, 2016, theentirety of which are each hereby fully incorporated by referenceherein.

TECHNICAL FIELD

This disclosure relates to a hearth oven such as an open oven used inrestaurant kitchens to bake pizzas and other items.

Open hearth ovens are generally known in the art and are frequently usedby restaurants to bake pizzas and other baked goods in a manner where achef can bake multiple pizzas (for example) at the same time and thechef can continuously access the baking volume of the oven, with anelongated spatula, without needing to open and close a door. Open hearthovens are also preferred because they allow the restaurant customer toview the baking of the foods therein and hearth ovens often are anaesthetic feature of a restaurant's kitchen, which is often viewablefrom the dining areas of the restaurant.

One conventional open hearth oven includes an enclosure that is formedfrom an insulated housing and includes an open front. The conventionaloven is heated by tube burners that are positioned at the sides of thehousing and/or at the back of the housing. The tube burners are operatedto provide the majority of the heat input within the oven. It is knownthat during operation significant temperature gradients often existwithin the enclosure and upon the baking surface, which necessitates thechef to frequently move the pizzas to be baked between certain positionswithin the oven to ensure proper baking. The conventional oven is formedwith a baking deck that is normally formed from a plurality of bakingbricks or other discrete pieces that are positioned together. Otherovens have baking decks that are believed to be formed from a compoundof alumina and silica. The necessary movement of pizzas within the ovenas they are baked often results in uneven baking and requires the chefto pay a significant amount of attention to move the pizzas as necessaryduring the baking process.

DETAILED DESCRIPTION OF THE DRAWINGS AND THE PRESENTLY PREFERREDEMBODIMENTS

Turning now to FIGS. 1-14, an oven 10 is provided. The oven may be openhearth oven or another type of deck oven. The oven 10 may be designedwith an open front that is continuously accessible during cookingoperations by the chef for convenience as well as to provide customerswith a view of the food being cooked within the enclosure 26 within theoven 10.

In some embodiments, the oven 10 may be provided with a rectangularcross-section (as depicted herein in the figures), while in otherembodiments, the oven 10 may be round, oval, triangular, trapezoidal, orother shapes (either geometric or arbitrary) depending upon the designconstraints of the restaurant kitchen and the desires of the customer.While the oven 10 depicted and specifically described herein is arectangular oven, one of ordinary skill in the art will easilycontemplate that the disclosed design can be successfully modified toother shapes with a thorough review of the subject specification andfigures and without undue experimentation.

In some embodiments, the oven 10 may be formed from a housing 20 that issupported on a stand or frame 18, or in other embodiments upon astructure provided by the restaurant facility. The frame may includereinforcing members that are configured to rigidly support the structureof the housing and to provide an open space for mechanical connectionsto the gas service (90, FIG. 6) that is used for the combustion withinthe burners of the oven (discussed below).

The housing 20 may include a front wall 23, a left wall 21, a right wall22, a rear wall 25, and a top, or ceiling, or roof 24, each of which, incombination with the baking deck 30, enclose a baking enclosure 26within which food is baked in the hot environment within the bakingenclosure 26 and due to contact with the top surface 32 of the bakingdeck 30. In some embodiments, the front wall 23 may include an opening23 a that allows access into the baking enclosure 26. The opening 23 amay be always open or may be selectively closable with a door (notshown) or with a block that can be put in place to selectively block theopening 23 a and can be removed to allow access through the opening 23.

In the embodiment depicted in the figures, the front wall 23, the leftwall 21, the right wall 22, the rear wall 25, and the roof 24 mayinclude multiple layers or multiple walls that are disposed between theportion of the respective wall that forms the barrier to the cookingenclosure and the structure that is disposed at the outer surface of thehousing 20. For the sake of brevity, the walls discussed herein refer tothe structure that directly encloses the baking enclosure 26 as well as,when present, other walls that are disposed outboard of the structurethat directly encloses the baking enclosure 26. In some embodiments,insulation is disposed between all or some of the multiple walls toprevent heat from the enclosure from transferring out of the enclosurethrough the walls, for efficiency purposes as well as to minimize thecontribution of the heat from the oven 10 in increasing the temperatureof the kitchen or other location where the oven 10 is disposed.

In some embodiments, the inner layers of the various walls (inembodiments where one or more of the walls are multiple layers) may beentirely planar, may have a portion that are planar (such as the portionthat is in contact with and extends from the upper surface 32 of thebaking deck 30 (discussed below)), or may be arcuate. Any discussion ofthe structure of the oven with reference to the orientation to any ofthe walls is with reference to a vertical planar wall that encloses aportion of the housing 20, but one of ordinary skill in the art willunderstand that the oven disclosed herein can be constructed with wallsof various shapes and orientations within the scope of this disclosurefor space constraints or for ornamental reasons.

The housing further includes a baking deck 30 that is configured tosupport the food product to be baked within the oven. The baking deckmay extend between the left and right walls 21, 22 and between the frontwall 23 and rear wall 25. The baking deck 30 may be supported by one,some or all of the walls and ultimately may be supported by the frame 18or other structure that supports the oven 10.

In some embodiments, the baking deck 30 may be cast in place with a formthrough a conventional casting process, with the form establishing abottom surface front edge, left edge, right edge and a rear edge of thebaking deck 30. The material forming the baking deck 30 may be mixed andpoured into the form to establish the baking deck with the desiredgeometry and the desired thickness. Once the material forming the bakingdeck 30 is poured the top surface 32 is established and smoothed usingprocesses well known in the art.

In some embodiments, the baking deck 30 may include one or moreapertures therewith that are provided during the casting process.Specifically, the baking deck 30 may be formed with elongate voids 35,36 that are formed on the left and right sides of the baking deck 30,respectively. The voids 35, 36 may be formed by establishing forms toprevent material being poured from resting in those locations. In someembodiments, the baking deck 30 may additionally or alternativelyinclude a rear void 37 that extends proximate to the rear wall 25. Thevoids 35, 36, 37 may be provided to allow for burners to extend throughthe baking deck 30 such that the heated combustion products from theburners are directed into the enclosure 26 to assist with baking thefood product disposed upon the top surface 32 of the baking deck 30.

In some embodiments, each of the voids 35, 36, 37 (in embodiments wherethese or other voids are provided) may include a respective shroud 45,46, 47 that extends above the top surface 32 of the baking deck 30. Theone or more shrouds, when provided, may provide a barrier between thetop surface 32 of the baking deck 30 and the respective void to preventfood crumbs, liquids, dirt, debris and the like that might be presentwithin the environment from falling into the void and potentiallyfouling the burners (discussed below) disposed through the respectivevoids. The left and right shrouds 45, 46, 47 may also provide structuralsupport for the burners that extend through the respective voids toproperly align and support the burners.

As depicted in FIGS. 2, 5, 6, 7, in some embodiments, one or both of theleft and right shrouds 45, 46 may be configured such that their sidewalls 45 a, 46 a are parallel to the respective facing side wall (21,22, 23, 24) of the housing 20, i.e. the side walls of the shroud extendvertically within the enclosure 26, i.e. with a line (Y,X) through theside wall 45 a, 46 a aligned in parallel to a vertical line 1000 throughthe center of cooking deck 30, i.e. the left to right centerline (FIG.7). In some embodiments, the respective side wall 45 a (46 a) that isclosest to the center of the cooking deck 30 is in this orientation, inother embodiments, the respective side wall 45 b (46 b) that is furtheraway from the center of the cooking deck 30 is in this orientation, andin some embodiments both side walls 45 a, 46 b (44 a, 44 b) of therespective shroud 45, 46 are in this orientation.

In other embodiments, depicted in FIGS. 8-10, the side walls 45 a (45b), 46 a (46 b) or one or both of the left and right shrouds 45, 46 maybe disposed at an acute angle (β for the side walls 45 a, 45 b; a forside walls 45 a, 45 b) with respect to the top surface 32 of the cookingdeck 30. In some embodiments, the acute angle may be about 75 degrees,or about 80 degrees, or within the range of between about 50 degrees to90 degrees, inclusive of all angles within this range, such as from 50to 80 degrees. In some embodiments, one or both of the side walls 45 a,45 b; 46 a, 46 b are disposed such that a horizontal vector component(T, \N) of a line through the side wall extends horizontally toward acenter 31 of the baking surface 30, while in other embodiments one orboth of the side walls may be disposed such that a horizontal vectorcomponent of a line through the side wall extends away from the center31 (not specifically shown, but one of ordinary skill in the art wouldunderstand that the shrouds would extend in the opposite direction asdepicted in FIG. 8, with the horizontal vector components extending inthe opposite direction as T and W in FIG. 8. In some embodiments, one orboth of the end walls 45 c, 46 c of the respective left and rightshrouds 45, 46 may extend at an acute angle, such that a horizontalvector component of a line through the end wall extends toward the rearwall 25 of the housing 20.

In some embodiments, the burners 60 (discussed below) are supported bythe shroud 45, 46 and the burners are aligned in the same orientation asone or both of the side walls 45 a, 45 b; 46 a, 46 b of the respectiveshroud, and/or in some embodiments the orientation of the end walls 45c, 46 c such that the heated exhaust from the burners (which heats thebaking enclosure 26) is directed toward the center of the environment,(or in another direction within the enclosure, such as the rear wall 25)which may assist with evenly maintaining the temperature within thebaking enclosure 26. The burners may be disposed at the same angle asthe angle of the respective wall of the shroud, or the burners may bedisposed at a different angle from the respective wall of the shroud. Insome embodiments, some burners may be aligned at an acute angle withrespect to a plane through the top surface 32 of the baking deck 30,while in other embodiments, some burners may be disposed in thisorientation, while other burners may be disposed vertically so thattheir heated exhaust gas leaves the burner vertically. One of ordinaryskill in the art will understand after a thorough review of the subjectspecification and figures, that one of ordinary skill in the art wouldbe able to design an enclosure and burners with the appropriate spacingand orientation to create a balanced heat environment within theenclosure with only routine optimization by the designer.

In some embodiments, the burners 60 that are disposed through one orboth of the left and right voids 35, 36 (and supported by the respectiveleft and right shrouds 45, 46 as well as in some embodiments additionalsupport structure disposed below the lower surface of the baking deck30) may be in-shot burners. In some embodiments, one or both of the leftand right voids 35, 36 may receive a plurality of in-shot burners, suchas 5, 7, 10, 11 in-shot burners (or in other embodiments, any number ofin shot burners between 2-10) disposed proximate to each other, in someembodiments disposed along a single line or in another geometricarrangement such as in two lines, or in a rectangular formation (orother formations as optimized by one of ordinary skill in the art). Theburners 60 may be disposed with consistent spacing between allneighboring burners or with different spacing between some burners.

As shown with reference to FIGS. 5a, 8a, 8b , the housing 20, andspecifically the roof and the baking deck are collectively disposed topromote circulation of heated air within the housing 20 to promote evenheating of food products disposed upon the baking deck at variouslocations. As shown in FIG. 8a , the heated combustion gas from the leftburners 60 leaves along path B, which initially leaves from the burnerin a path generally parallel with the orientation of the burner upon thebaking deck, and then is urged toward the left to right centerline ofthe housing, in some embodiments due to the angle of the roof 24 of thehousing where the combustion air interacts with the roof (as discussedbelow). Similarly, the heated combustion gas from the right burners 60leaves along path A, which initially leaves the burner in a pathgenerally parallel with the orientation of the burner upon the bakingdeck, and then is urged toward the left to right centerline of thehousing, in some embodiments due to the angle of the roof of the housingwhere the combustion air from the right burner 60 interacts with theroof. As shown, proximate to the left to right centerline 1000 of thehousing, when both the left and right plurality of burners 60 areoperating the paths B and A interact with each other at location C. Thepaths B and A when interacting with each other are urged downwardlytoward the baking deck 30, where a portion of the combustion air flowstoward the burners again (D, E) and another portion of the combustionair flows out of the oven through the exhaust F. The looping flow ofcombustion air as depicted in FIG. 8a promotes even heating over theentire surface of the backing deck. One of ordinary skill in the artwill understand (with a thorough review of the subject specification)that the flow paths A, B, D, E depicted in these figures are schematiconly and simplified, and while combustion air is urged into these paths,some of the air flow is more complicated that this simplified path.

In some embodiments, the roof 24, and specifically portions of the roof24 that are above, or more specifically in-line with the exhaust fromthe respective left and right in-shot burners 60, is disposed at anacute angle γ with respect to the top surface of the baking deck 30.Specifically, the roof 24 is formed such that combustion gas reachingthe roof from the plurality of in-shot burners 60 is urged toward theleft to right centerline 1000 of the baking deck 30 (as schematicallyshown as flowpaths A, B in FIG. 8b ). In some embodiments, the acuteangle (γ) may be the same angle as the angle of the respective burner 60positioned below the portion of the roof, while in other embodiments theacute angle γ may be a different angle than the angle of the burner 60disposed below the portion of the roof, and in still other embodimentsthe roof may be an acute angle γ, while the burners are perpendicular tothe top surface of the baking deck 30.

In some embodiments, the portion of the roof generally above therespective left and right plurality of burners (and specifically,generally in-line with a line from the burners) may have a curvedorientation, with a changing angle along its length, which may becontinuously changing (with the same curvature along its length) ordiscontinuously changing, such that the magnitude of the acute angle isdecreasing as the roof travels toward the left to right centerline ofthe roof. One of ordinary skill in the art with a thorough review ofthis specification will appreciate that the shape of the roof from abovethe respective left and right burners and to the left to rightcenterline of the housing will be provided to guide combustion air fromthe left and right plurality of in-shot burners toward the center of thehousing, so that the combustion gas flows from both the left and rightplurality of burners ultimately interacts with each other, andparticularly in some embodiments interacts to create the looped flowpaths A and B depicted in FIG. 8b . In embodiments where the left andright plurality of burners 60 are disposed at acute angles α, β withrespect to the top surface of the baking deck (FIG. 7), the roof abovethe burners may be parallel to the baking deck and the initial angle ofattack of the combustion air from the burners may urge the combustionair (from both the left and right in-shot burners) toward the left toright centerline of the housing due to the relative angle of thecombustion flow with respect to the roof 24. One of ordinary skill willunderstand that an optimization of the shape of the roof in order topromote the lopped flow paths A and B would only be a product of routineoptimization upon a thorough review and understanding of thisdisclosure.

The baking deck 30 is best show in FIGS. 2, 3, 7, 12, and 13. Asdiscussed above, the baking deck 30 may include a flat horizontal topsurface 32, which is the surface upon which to be baked within the ovenrests. The baking deck 30 may be formed as a continuous monolithicmember that is formed without any seams or joints therein. In someembodiments, the baking deck 30 may be formed by cement that is pouredinto a form that established the geometry of the baking surface 30 aswell as establishes the voids 35, 36, 37 when provided as discussedabove. The baking deck 30 may be formed as silicon carbide cement. Inone representative embodiment, the baking deck 30 may be formed from asilicon carbide cement with the following formulation (by percent):SiC—53.3%; Al₂O₃—32.3%; SiO₂-11.9%; Fe₂O₃—0.4%; CaO—0.9%; TiO₂-0.7%;Alkalies 0.2%. In some embodiments, all of these may be present but atdifferent percentages, such as about 53% or between 50-55% SiC, such asabout 32% or between 30-35% Al₂O₃, such as about 11% or between 10-15%SiO₂ with the other percentage of the other components modifiedaccordingly. The term “about” is specifically defined here to includethe value referred to as well as all percentages within plus or minus 2%of the value referred to. In other embodiments, the one or more of theabove may be missing and replaced with a similar compound as would beunderstood by one of skill in the art. In still other embodiments, theformulation may be different from the above with some compounds missingand replaced with other compounds. One of ordinary skill in the art witha thorough review of this specification will understand potentialmodification of the formula of the cement and be well equipped to modifythe formula based upon desired properties of the cement used to form thebaking deck 30.

In some embodiments, the baking deck 30 may be formed with one or aplurality of thermocouples 130 that are disposed within the baking deck30. As shown in FIGS. 12-14, the thermocouples 130 are disposed withinthe baking deck 30, such as embedded below the top surface 32 and abovethe lower surface 33. The one or a plurality of thermocouples 130 arepositioned within the form before the cement material is poured into theform so that, once the material is poured and cured there are no air orother gaps between the material forming the baking deck 30 and thethermocouples 130.

In one representative embodiment, multiple thermocouples 130 a, 130 b,130 c may be positioned vertically on top of each other and embeddedwithin the baking deck 30 and supported by a single assembly 140. Insome embodiments, the assembly 140 may be initially surrounded by aprotective layer 142 (FIG. 14) that surrounds the structural portions ofthe assembly 140 with the thermocouple leads extending out of theprotective layer and buried within material of the cast baking deck 30.The protective layer 142 may protect the components of the assemblyduring the casting or curing process. In some embodiments, theprotective layer may remain with the assembly, or in other embodiments,the protective layer may melt during the hot curing process. Eachthermocouple 130 a, 130 b, 130 c may be attached to wires 139 that runthrough the baking deck 30 and out of the bottom surface 33 of thebaking deck and to the controller 1001. In some embodiments, thethermocouple wires 139 extending from the thermocouples are secured intolocation with a rigid tube 148, and in some embodiments, foam insulation149 is wrapped around the tube to act as an expansion joint for thetube.

In embodiments where multiple thermocouples are provided in a singleassembly, the multiple thermocouples may extend into the baking deck 30in a stacked vertical fashion to allow for heat that is flowingvertically through the baking deck 30 to consecutively interact with thestacked thermocouples 130. In one embodiment, a first thermocouple 130 amay be disposed within the baking deck and proximate to the top surface32 of the baking deck, such as within 0.25 to 0.5 inches of the topsurface 32. A second thermocouple 130 b may be disposed at or proximateto a middle of the baking deck, such as substantially (or exactly)equidistant from the top and bottom surfaces 32, 33 of the baking deck.In some embodiments, a bottom thermocouple 130 c may be provided that isdisposed proximate to the bottom surface 33 of the baking deck, such aswithin 0.25 or 0.5 inches. One of ordinary skill in the art with athorough review of the subject disclosure will easily understand that,for the top thermocouple 130 a it is often desired to position thethermocouple 130 a as close as possible to the top surface 32 of thebaking deck 30 so that the temperature data from that thermocouple willbe as close as possible to the actual surface temperature of the bakingdeck 30 at that position. It will be appreciated that the distance belowthe top surface may be a function of the properties of material used tomake the baking deck 30, such that the required strength and durabilityof the baking deck 30 is maintained with the amount of material betweenthe top surface 32 and the thermocouple being minimized, and one ofordinary skill would be able to optimize (i.e. minimize) that distancewith routine testing and optimization of the design and without undueexperimentation.

The thermocouples 130 may extend far enough from the assembly 140 intothe baking deck 30 so that the heat transfer effect of the assembly onthe measured temperatures by the thermocouple can be neglected by thecontroller. The controller 1001 may include a microprocessor that isprogrammed to monitor independently the temperatures (and the change intemperature) of the vertically stacked thermocouples 130 to understandthe heat flow rate through the baking deck 30 at that location upon thebaking deck and selectively operate the burners (the side in-shotburners 60 and/or the burners 70 below the baking deck 30) to controltemperature proximate to that location as warranted.

In some embodiments, at least one thermocouple 130 is positioned alongthe left to right center line of the baking surface, or if not exactlyalong the geometric centerline within a short distance (such as one halfinch (FIG. 13), or one or two inches) from the geometric left to rightcenterline, such as when mechanical clearance is not available toposition the thermocouple at the geometric center 303 (FIG. 13) of thebaking deck 30 (position N in FIG. 13). In some embodiments,thermocouples 130 may be disposed outboard of the center thermocouple130 on one or both of the right and left sides of the centerthermocouple, such as in positions H, J and/or positions K, L of FIG.13. In some embodiments, some or all of the respective thermocouples maybe positioned proximate to a front to rear centerline along the bakingdeck 30. In other embodiments, some or all of the thermocouples 130 maybe positioned proximate to a line 302 positioned between the front wall23 and the front of the rear void 37. One of ordinary skill in the artafter a thorough review of the subject specification and figures willeasily comprehend that centered thermocouples (front to back/rear void;left to right) may provide a reliable representation of the temperaturewithin enclosure and the baking surface 30 such that the controller 1001(FIG. 12, schematic) may be configured to operate burners 60 (discussedbelow) within the oven in order to maintain the desired temperaturetherein.

Additional thermocouples (disposed outboard of the central thermocoupleor in other positions, such as proximate to the left to right centerline 303 and closer to the front wall and/or back wall 23, 25) (e.g.position M of FIG. 13) may be used by the controller 1001 to furthercontrol the operation of the burners based upon the more localizedtemperature information provided to the controller by multiple burners.In some embodiments, thermocouples or other types of temperature sensorsmay be positioned in other locations within the oven, such as on one ormore side walls, the roof, within the exhaust. These thermocouples mayadditionally or alternatively provide temperature information to thecontroller 1001, which may be used by the controller to control theoperation of the burners 60, 70 either solely, or in some embodiments inconjunction with stored information based upon a recipe or user desiredtemperature setting.

In some embodiments, the oven 10 may include burners 70 that aredisposed below the baking surface 30 such that the heat generated by theburners 70 is transferred to the baking surface through the bottomsurface 33 and is transferred through the baking surface 30 byconduction. One of ordinary skill in the art will comprehend with athorough review of the subject specification and figures that one burner70 may be provided below the left to right centerline of the bakingsurface 30, or in other embodiments, two burners 70 may be provided bothoutboard of the left to right centerline, such as at equal spaces fromthe left to right centerline.

In some embodiments, the burner 70 within the box is positioned suchthat its heated combustion products are directed into a box 72 that isbelow the baking surface 30 such that flow through the box flows alongthe bottom surface 33. Heat from the combustion air may be transferredto the baking surface by convection, with that heat then flowing throughthe baking surface and to the top surface 32 by conduction, withcombustion air ultimately being exhausted away from the box 72. The sizeof the box 72 may be shaped and sized to maximize the time thatcombustion air is present within the box 72, to maximize the heattransfer to the baking deck 30 for efficiency purposes, while stillallowing exhaust of combustion air from the box 72 as needed. Thecontroller 1001 may be configured to selectively operate the one or moreburners 70 based upon the measured temperature within the thermocouples130 that are proximate to or above the respective box 72, as well asbased upon a measured rate of change of the measured temperature. Inembodiments where the burners 70 are maintained with a box 72, separateboxes 72 that support separate burners 70 may be positioned on oppositesides of the left to right centerline through the baking surface.

In some embodiments, the box 72 is disposed in conjunction with the rearvoid 37 in the baking surface, and specifically such that combustion gasfrom the box flows through the rear void 37 and into the bakingenclosure 26, as depicted schematically as flow path H in FIGS. 2 and 5a. This heated combustion gas additionally serves to heat the bakingenclosure 26. In embodiments where there are two boxes 72 provided(which in some embodiments are positioned on opposite sides of the rightto left centerline of the baking surface), each box 72 is positioned incommunication with the baking enclosure 26 via separate paths throughthe rear void 37.

In some embodiments, a burner 80 may be provided within the oven 10 andspecifically may extend through a rear void 37 and a rear shroud 47. Theburner 80 may be constantly operating during operation of the oven toprovide display of a flame within the oven for ornamental aspects, andthe burner 80 may or may not provide a meaningful input of heat to theenclosure 26. In some embodiments, the burner may be a tube burner witha number of apertures to spread the flame generated by the burner alonga horizontal length of the burner 80 for visual purposes. In otherembodiments, in-shot burners 60 may be provided through the rear void 37and those burners may also be operated by the controller for asignificant addition of heat to the enclosure 26.

The controller 1001 may operate the oven in various duty cycles of theburners 60 that extend through one of both of the left and right voids35, 36 and the burners 70 that are disposed below the bottom surface 33of the baking deck 30. The duty cycles may be based upon feedbackcontrol based upon the information received from one or more of thethermocouples 130 that are provided within the baking deck 30.

Through experimentation, it has been determined that the oven 10 asdisclosed herein preforms significantly better than the conventionaloven discussed above, with respect to thermal performance for the sameheat input as well as with respect to providing a significantly moreuniform baking temperature throughout the top surface of the bakingdeck. This improved performance is beneficial for many ways, such ashigher baking deck surface temperatures for a given heat input, and moreuniform surface temperatures at different positions upon the bakingdeck. This second benefit may allow the chef to cook more food productssimultaneously upon the cooking deck 30 due to the lessened need to movethe pizzas during cooking as with the conventional oven (due to thediffering surface temperatures found during operation of theconventional oven), which allows the chef to potentially cook morepizzas at the same time because less time and attention can be paid toeach pizza during the cooking process.

Moreover, it has been determined that the oven disclosed herein with abaking deck made from the silicon carbide cement composition discussedabove is significantly better than oven decks that are made from othercompositions such as Alumina silica, due to the increased thermalconductivity of the silicon carbide cement. For example, the followingdata was derived based on testing an oven with the same geometry andheat input to compare an Alumina/silica deck with a deck of the siliconcarbide composition. The data provided below presents the averageinternal temperature of the deck at two positions, with one measuringthe center of the deck and the second measuring 0.5 inches from the topsurface of the deck. Both decks were heated with the same underfloorburner and the same burners operating within the cooking volume. Tablesthat depict the improvement (the minimized difference in temperatureover time are presented below.

As can be seen in Tables 1 and 2, during heat up the difference intemperature between the internal temperature of the baking deck and thesurface temperature gets to a negligible difference (1 or less degreeF.) within 20 minutes of initial heat up, while the Alumina Silica Decknever reaches a negligible difference between internal temperature andsurface temperature. Because the deck with the silicon carbidecomposition reaches a generally uniform temperature between the internaland the surface temperature, the deck can transfer heat, in eitherdirection relatively rapidly as needed during cooking operations tomaintain a relatively constant baking temperature, either from thesurface to the internal, or from the internal upward toward the surface,i.e. when a new relatively cold pizza is placed upon the baking deck.The baking deck that is formed from a continuous piece also allows forheat to transfer both vertically as well as horizontally within thebaking deck for maintaining a uniform surface temperature during cookingoperations.

It has also been experimentally determined that replacing theconventional tube burners that heat the cooking enclosure with aplurality of in-shot burners that extend through apertures in the bakingdeck significantly improves the cooking performance of an oven.Specifically, because in-shot burners are known to burn with a much moreefficient burn than tube burners, which, in combination with the flowpatterns generated within the cooking enclosure (A, B, D, E) discussedabove, is believed to provide a significantly more uniform temperatureacross the cooking surface, as measured by thermocouples that are spacedalong the baking surface.
